Most of Carson was built in the late 1960s and 1970s, and a lot of the locks on those homes are original or close to it. A worn Kwikset key-in-knob or a single-cylinder deadbolt with a standard keyway can be opened by someone with basic tools and a little patience. High security hardware is built to make that much harder. The cylinders resist picking and bumping, hardened inserts resist drilling, and the keys are restricted, so a copy can't be cut at just any kiosk.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has spent decades working on the kinds of doors found around Carson: stucco tract homes, garden apartments along Avalon and Carson Street, manufactured homes in the city's mobile-home parks, and commercial doors in the industrial areas. We are a mobile service only. There is no storefront to visit, because we bring the tools and hardware to your property.

A high security lock is only as good as the door and strike it is mounted on. So we look at the whole entry point, not just the cylinder. Sometimes the right answer is a full high security deadbolt. Sometimes it is a rekey, a reinforced strike plate, or a better latch on a sliding door. We will tell you what makes sense for your door and what would be money spent for little gain.

How it works in Carson

  1. 1

    Talk through what you are protecting

    Call (323) 997-8867 and tell us about the property: a single-family home, a manufactured home, a garden apartment, or a commercial space. We ask about recent break-in attempts, who holds keys, and whether you want one key for every door.

  2. 2

    Assess the doors and existing hardware

    On site, we check the door material, thickness, frame, strike plate and current lock. Lightweight mobile-home doors and aging hollow-core or worn wood doors need different solutions than a solid-core door on a stucco tract home.

  3. 3

    Choose the right level of protection

    We explain options such as pick-, bump- and drill-resistant cylinders, restricted keyways with controlled key duplication, and reinforced strikes. You decide how much security fits your situation and budget.

  4. 4

    Install and fit the hardware

    We install the new locks, reinforce the strike and frame where needed, and test the throw and latch so the bolt seats cleanly. If your doors share a key, we can set them up that way.

  5. 5

    Test, hand over keys, and explain duplication

    We test every lock with the new keys, confirm the doors close and secure smoothly, and explain how key duplication works with restricted systems so you know how to get extra keys safely.

What affects the price

  • The grade and brand of the high security cylinder or deadbolt, since restricted-keyway systems with drill-resistant components cost more than standard hardware.
  • How many doors you want secured and whether you want them all keyed alike on a single key.
  • The condition of the door and frame, including whether a strike plate, reinforcement or door repair is needed for the lock to perform properly.
  • The type of door, such as a lightweight manufactured-home door, an aluminum sliding patio door, or a commercial roll-up door, which can require specialty hardware.
  • Whether the work is an emergency after a break-in attempt or lockout, or a scheduled upgrade, and the time of day the call comes in.
  • Extra restricted keys and any key-card or authorization requirements tied to the system you choose.

Why Carson chooses us

  • Fully mobile 24/7 service: we come to your Carson home or business instead of asking you to drive anywhere.
  • In business since 1987, with owner David Shar personally involved in the work.
  • We look at the door, frame and strike, not just the lock, because a strong cylinder on a weak door does little.
  • Experience with the local housing mix, from 1970s Kwikset and Schlage hardware to mobile-home locks and commercial cylinders.
  • We recommend what fits and say so when a rekey or reinforcement is enough, rather than selling the most expensive option.
  • We explain restricted-key duplication clearly so you know who can and cannot copy your keys.

High Security Locks across Carson

Carson's tract neighborhoods, such as Scottsdale and Carriage Crest, are full of ranch and split-level homes from the late 1960s and 1970s. Many still have their original key-in-knob locks and single-cylinder deadbolts, which are good candidates for an upgrade. Homeowners in Victoria and near Dominguez Hills often ask us about keying all exterior doors alike while replacing weak hardware, and about reinforcing sliding patio doors whose latches have worn over the years. In ZIP codes like 90745 and 90746, that mix of older tract homes and garden apartments makes door-by-door assessment important.

Carson also has a notable number of mobile and manufactured-home parks, where doors are often lighter and use different lock styles. We can replace mortise-style mobile-home locks and work with the hardware that fits those doors. On the commercial side, the industrial areas along Alameda Street and near the I-405 and SR-91 corridors have warehouses with roll-up doors and commercial cylinders where stronger, restricted-key systems make real sense, especially after a break-in attempt. Businesses in ZIP 90810 and 90745 often need broken keys extracted and cylinders replaced the same day.

Whether you are near Dignity Health Sports Park, close to California State University, Dominguez Hills, around SouthBay Pavilion, or just off the I-110 on Carson Street, we travel to you. Call (323) 997-8867 any hour and we will plan the job around your property.

High Security Locks in Carson — FAQs

What makes a lock high security?
High security locks use cylinders designed to resist picking, bumping and drilling, and often pair them with restricted keys that cannot be copied freely. They also usually come with hardened components and stronger bolts. Call (323) 997-8867 to discuss which options suit your door.
Is a high security lock worth it on an older Carson tract home?
Often yes. Many 1970s homes still have original Kwikset or Schlage hardware with standard keyways that are easier to defeat. Upgrading the deadbolt and strike plate is one of the more effective ways to improve security on those doors.
Can you install high security locks on a mobile or manufactured home?
Yes, though the door matters. Mobile-home doors are often lighter, and some use mortise-style locks. We check the door and frame first and choose hardware that fits and holds up. We can also help with park-gate access hardware questions.
Can all my doors use one key?
In most cases, yes. We can set up exterior doors to be keyed alike so you carry a single key. We will tell you if any door needs different hardware to do this.
Who can copy a restricted high security key?
Restricted systems limit duplication to authorized sources, usually requiring proof of authorization. This prevents casual copying at a hardware store or kiosk. We explain exactly how it works for the system you choose.
Do you handle businesses and warehouses in Carson?
Yes. We handle commercial cylinders, roll-up door locks, broken key extraction and post-break-in upgrades for businesses, including industrial areas along Alameda Street. Call (323) 997-8867 and describe what you have.
Will a new lock help if my door frame is weak?
Only partly. A strong lock needs a solid door, frame and strike plate. We inspect these and recommend reinforcement where needed so the whole entry point works together.
Do you offer emergency service, and do I have to come to a shop?
We are mobile only and available 24/7, so there is no shop to visit. We come to your property for lockouts, break-in repairs and upgrades. Call (323) 997-8867 any time.
